This invention relates to the treatment of peat for the purpose of drying it quickly so as to make it suitable as a manure or fertilizer or for other industrial purposes such as in ingredient for food or cattle, sheep etc. or as a litter.

The usual method of treating peat for the above purposes is, briefly, to dig up the peat in slabs or sods which are stacked and often built into large piles to dry, after which and when thought to be sufficiently dry, the slabs or sods are broken up according to the required product.

This usual method is very slow because of the great amount of time required for the drying, much of which is nullified in wet weather. As peat is of vegetable origin and contains organic matter which is gradually broken down into humus, it is in this state very retentive of moisture and becomes owing to this wet state anaerobic and acid. The present method of The moisture content of the peat when broken up is usually reduced by about 10%. The initial drying is carried out to an extent sufficient to increase the moisture loss by about 20% of the original amount and the final drying subsequently to the ridging is continued until the moisture content is reduced to about 50% of the original amount. .o

Instead of sowing the green crops I may spread newly cut grass, greens or the equivalent over the peat bed and plough or otherwise cultivate it into the peat in much the same way as if the grass etc. had grown from the peat. If I use on the prepared peat surface green stuff which is not grown on the peat the use of the fertilizer is not necessary.

In either case decomposition is rapid and efiects satisfactory dehydration and when the crops are 1;; grown on the bed the roots assist aeration and drainage of the said bed.

The material in the heaps may be used alone, or with green stuff, for the purpose of preparing vegetable matter.
